In Lincoln, California, Jack Sales spoke to the Lincoln Hills Astronomy Group about light pollution. He joined the International Dark Sky Association back in 1993 and in 1996 started up the first California branch. Since then he’s received numerous awards rewarding him for his efforts in promoting education about light pollution and dark skies.

As long as it takes, and as many times as it takes, to educate people about the effects of light pollution, may there continue to be many more people following in the footsteps of Jack Sales. It’s important to present this in a non-threatening and non-judgmental way so that people will hear the message.

A light pollution primer: our sleep and the hormonal cycles of all living creatures is affected by light pollution, our circadian rhythms depend on having periods of darkness. Our stars and our night sky has been replace with an urban glow blotting out the stars and the night sky. The stars are still there, we just can’t see them.
